&gt;I am looking for a ford 9" rear end 3 to 1 ratio, at the 52" to 54" wide
&gt;range ?
&gt;
&gt;
&gt;I live in El Cajon Ca & have a 1973 Datsun pick up that my SON & I are
&gt;building up as a project car for him , that i have some gearing
&gt;problems/questions on ......
&gt;
&gt;I put a 1979 chevy NOVA inline 250 6cyl low end motor motor (its stk rear
&gt;end was 2.57) in my datsun pick up that has 4.875 to 1 ratio stk & I can
&gt;only go only approx 45 mhp
&gt;at about 3500 RPM
&gt;
&gt;Obviously I want to make this swap work ! , the datsun rear end is probably
&gt;to wimpy for the bigger motor any way ! ? so going to a bigger rear end
&gt;would be
&gt;the smart choice in the long run any way .......now my dilima......I'm not
&gt;looking to spend a bunch of money on a rear end so I woul desire a
&gt;affordable route ?
&gt;
&gt;-which would probablly be a rear end out of a car in the junk yard or ? I
&gt;saw a listing chart that said
&gt;* 63-69 falcon 52" wide
&gt;* 63-69 comet 52" wide
&gt;* 63-65 fairlane 52" wide
&gt;* 65-66 mustang 52" wide
&gt;* 63-69 comet 52" wide
&gt;* 66-69 fairlane/cyclone 54" wide
&gt;* 67-70 mustang/cougar 54" wide
&gt;* 60-64 ford/mercury 54" wide
&gt;
&gt;So I was thinking of changing the rear ends ?
&gt;
&gt;I was told my best bet would probably be to go with a ford 8" or 9" rear end .
&gt;My existing rear end width is 53" wide so a 52" to 54" would be perfect ?
&gt;
&gt;I think for what I need in desired operating speed , desired operating RPM,
&gt;with my tire size/dia (29"tall) a 3 to 1 ratio range is
&gt;appropriate/desired.
&gt;
&gt;The old Nova rear end was 2.57 to 1 & my existing datsun rear end is 4.875
&gt;to 1 .....so going to approx 3 to 1 is where I think I am headed for 65 MPH
&gt;freeway & good general around town
&gt;
&gt;If you have any suggestions on my quest to solve this dilima I greatly
&gt;respect your opinion & help ! (web sights or phone #'s appriciated)
&gt;
&gt;thanks so much for your help Dale smith El Cajon ca 619-691-2270

Personally I think a 9" is overkill, they are harder to find because all
the drag racers and street rodders have grabbed most of them. The Ford
8" is a very good rear and can handle way more torque than your engine
can put out (it was used on many v8 cars) and are a lot cheaper. The
last 8" that I bought I paid $50 with the right gears and good brakes.
For highway cruising, the 2.79 rear that was common in Mustangs and
Falcons may be ideal. Some of them were also available in 3.0 to 1.
